Let's roll up our sleeves and solve this. We have 106 and we're going to multiply it by 39, essentially adding 106 to itself 39 times.
Step 1: 0 + 106 = 106
Step 2: 106 + 106 = 212
Step 3: 212 + 106 = 318
Step 4: 318 + 106 = 424
Step 5: 424 + 106 = 530
Step 6: 530 + 106 = 636
Step 7: 636 + 106 = 742
Step 8: 742 + 106 = 848
Step 9: 848 + 106 = 954
Step 10: 954 + 106 = 1060
Step 11: 1060 + 106 = 1166
Step 12: 1166 + 106 = 1272
Step 13: 1272 + 106 = 1378
Step 14: 1378 + 106 = 1484
Step 15: 1484 + 106 = 1590
Step 16: 1590 + 106 = 1696
Step 17: 1696 + 106 = 1802
Step 18: 1802 + 106 = 1908
Step 19: 1908 + 106 = 2014
Step 20: 2014 + 106 = 2120
Step 21: 2120 + 106 = 2226
Step 22: 2226 + 106 = 2332
Step 23: 2332 + 106 = 2438
Step 24: 2438 + 106 = 2544
Step 25: 2544 + 106 = 2650
Step 26: 2650 + 106 = 2756
Step 27: 2756 + 106 = 2862
Step 28: 2862 + 106 = 2968
Step 29: 2968 + 106 = 3074
Step 30: 3074 + 106 = 3180
Step 31: 3180 + 106 = 3286
Step 32: 3286 + 106 = 3392
Step 33: 3392 + 106 = 3498
Step 34: 3498 + 106 = 3604
Step 35: 3604 + 106 = 3710
Step 36: 3710 + 106 = 3816
Step 37: 3816 + 106 = 3922
Step 38: 3922 + 106 = 4028
Step 39: 4028 + 106 = 4134

So, 106*39 = 4134
